摘　　要：大直径超长灌注桩在一些体量大、难度高的重点工程中得到了广泛应用。齐鲁黄河大桥主墩桩基采用超长大直径灌注桩,超长大直径灌注桩桩基成孔的质量控制是项目前期建设的重点和难点,针对这一难点进行了系统地阐述,为黄河地带的工程施工提供一些参考。Large-diameter and super long cast-in-place piles have been widely used in some large-scale and difficult key projects.The pile foundation for main pier of the Qilu Yellow River Bridge adopts super long large-diameter cast-in-place piles.The hole forming quality control of super long and large diameter cast-in-place pile foundation is the key and difficult point of the early stage construction of the project,which is systematically expounded in the paper,hoping to provide some help for the project constructions in the Yellow River area.
